摘要

对摩擦摆基础隔震结构进行了地震反应分析,研究了上部结构周期对结构地震反应的影响.结果表明,随着上部结构刚度的减小,上部结构周期增大,摩擦摆支座位移逐渐减小,上部结构的加速度反应和楼层剪力逐渐增大.
The analysis on the seismic response of base-isolated structures with friction pendulum system is carried out,the effect of the superstructure periods on the seismic response is studied.As the stiffness of the superstructure decreasing,the periods of the superstructure increase,so the bearing displacements will diminish,and the acceleration and the story shear of the superstructure will increase.
